I like this proposal but there is a problem in the patch:

      (when (string-match " +$" m)
         (propertize (substring m (match-beginning 0)) 'face 
'trailing-whitespace))

This is a no-op.  But maybe it is good to remove this code because the
failed trailing whitespace is highlighted in the new face isearch-failed.
We could change its background to more strong color, e.g. to something
like is used in Firefox failed search, so failed space will be more visible.
